SPECIFICATION forming part. of Letters Patent No. 342.278. dated May 18,1886.

(No model.)

To all whom t may concern:

Be it known that I, EDWIN E. BEAN, of Boston, in the county of Suffolkand State of Massachusetts, a citizen of the United States, haveinventedcertain new and useful Improvements in Pegging-llachines, of which thefollowing is a specification.

My present invention relates to improvementsin pegging-machines forboots and shoes, substantially of the character shown in Letters PatentNo. 135,681, to Erastus VoodWard; and it consists in improvements ofmachinery of that character, whereby its efliciency and usefulness areincreased.

In machines of this class the work is held or supported on what iscalled a horn, this horn being adapted to be swung partially or entirelyaround, so as to present all parts of the Work successively to theaction of the machine.

In the operation of the machine a hole is first punched in the work andya wire peg is cut off by themachine to a certain length from alongerpiece of Wire. Then this peg is carried over to and drivenin the holeand there headed, clinched, or set, so as to make a secure and firmfastening. Finally, the Work is fed along aproper distance for the nexthole to b punched.

My present invention relates mainly, first, to improvements in theapparatus for feeding the Wire and cutting off the peg; second, toimprovements in the apparatus for carrying the cut peg under the driverand driving it; third, to improvements in the mechanism whereby thenecessary motions are given to the punching and driving tools, and,fourth, to improvements in the construction of the machine whereby aclinching or heading of the peg on the inside is accomplished in a moreeffective manner than before.

Figure 1 is a side elevation of my machine. Figs. 2, 3, 4, 5, 6, 7, 8,and 9 are details of different parts. Fig. 10 is an enlarged side viewof the upper part, taken from the same side that Fig. 1 is taken. Fig.11 is an enlarged side View of the upper part, taken from the sideopposite to that of Figs. 1 and 10. Fig. 11a is a detail'showing the camand its immediate adjustments for operating the headof the upper part ofmy machine. Fig. 13 is a detail. Fig. 14 is an enlarged front view ofthe upper part of my machine, a part of the sliding plate being cut out,so as to show the recess on its rear side and the cam that works it.Fig. 15 is a plan view of a part of the head ofthe machine. Fig. 16 isan enlarged side view of a part shown in Fig. 11, and relatesparticularly to the wire feeding and cutting-oft` mechanism. Fig. 17 isa section on line a: x of Fig. 16.

The shaft B is the main source of power in the machine, powerbeingapplied through the pulley B. The up-and-down motion of the awl, thecarrier D', which is also connected with and moves up and down themechanism for feeding and cutting off the peg-wire, and of the driverand driver-bar E E is derived from a rocker arm or lever, C3, mounted onthe auxiliary rockershaft C', which is rocked from the main shaft by thelever C2, Working in a camvgroove on the wheel-cam C. This is bestindicated by dotted lines in Fig. 14. The to-and-fro motion of the awland driver,whereby each is brought successively over the work at thepoint where the peg is to be driven, is obtained by mounting them in asliding car riage or plate, (best shown at A", Fig. 10,) which is slidback and forth by a cam, B2, mounted on and driven by the main shaft,also by means of a lever, H, operated by the motion of the plate A2 andconnected at its outer or moving end with a second sliding plate, H".This second plate, which is perforated at H5 to receive the cut peg andacts as a carrier for it, is brought up to and carried back from theproper point over the Work to deliver the 'peg in place under the driverto be driven into the hole previously formed by the aWl, and is thencarried back to receive another peg. The heading or clinching action,which should occur simultaneously with the driving of the peg, is alsoobtained from the main shaft B by means of the cam-wheel P12, lever P,(see Fig. 11^,) mounted on the auxiliary shaft G, connecting-rod P, andsystem of bell-crank levers, (best shown in Fig. 1,) causing a movinganvil or clincher, M, to come up through the horn'and meet the inner endof the peg, thereby clinching it.

ing device. Fig. 12 is an enlarged rear view The timing of the machineis as follows:

IOC)

The first operation is the feeding of the wire and cutting off of thepeg, and simultaneously the punching of a hole through the work; second,the withdrawal of the awl and the return of the peg-feeding mechanism toits highest point, third, the lateral movement of the awl, driver, andcut peg, whereby the awl is moved away from its position over the holein the work, which is taken in turn by a carrier containing the cut peg,the driver at the same time being brought into a position immediatelyover the peg to drive it into the work; fourth, the driver descends, anda't the same time the clincher ascends to Ldrive and clinch the peg,after which the driver is raised or withdrawn; fifth, the peg-carrier,awl, and driver are returned to their original positions, and the workis simultaneously fed forward a distance corresponding to the intervalbetween two pegs.

I will first describe the mechanism for feeding the peg-wire and cuttingoff the peg, and also in connection with it the device whereby I insurethe automatic regulation of the length of each peg to correspond withthe thickness of the work at that point where the peg is to be driven.The bar Ct, Figs. 14 and 16, as it ascends, acting through the toggle C5C, Fig. 16, causes the levers G C, which swing upon a pivot, C7, to openthe jaws C CH, and thus be freed from the wire. Now, the continued 1notion (the wire being held by a friction-pawl, c', Figs. 16 and 17) ofthe bar C* will draw the jaws G8 C8 up to the required distance for afeeding-down action. This feeding-down action is effected by themovement of the arm D, which is secured to the awl-bar D', Fig. 14, theend of which passes into a slot, el, in the bar Gt, and thus causes thesaid bar C4 to move up and down with the awl-bar D', except that in thebeginning of the downward stroke the bar C* does not begin to move, asthe slot c2 is longer than the arm D is wide. In other words, Ihaveprovided what is called lost motion.77 As the bar C* moves down, it,acting through the toggle C5 C, moves the levers C" C downward withoutclosing thejaws C8 Us, as the guides C9 G" on the adjustable plate MTprevent this action; but as soon as the lower ends of the toggles G5 C5have descended below the guide-pieces C9 C, then they are free to openthe levers C C", and thus cause t-he jaws Cs C8 to grasp the wiresuciently to feed it downward. This grasping pressure remaining the sameuntil the upper ends of the levers C C have passed below the studs G1C1", then the levers C C are free to be expanded by the toggle actionofthe toggles G5 C5, and thus close the jaws Cs C8 with different motionto cut off the wire. The function of the guide-pieces C9 is to regulatethe feeding of the peg-wire just the proper distancel to give a pegwhich shall correspond in length with the thickness of the work at thepoint where it is to be driven, and I will now describe the mechanism bywhich this is accomplished. As has been said, the gripping action of thelevers Cn 'fixed position.

will not comeinto play until they have passed beyond the guides C".These guides are connected through the plate MY with a sliding rod, M,operated by a link, M", worked from a rockershaft, M, which in turn isrocked by an arm,1 u, attached to and driven by a connecting-rod, K.This is illustrated in Figs. 1, 11, and 16. The lower end of thisconnecting-rod K" is carried upon onearm of a lever, K6, the other endof which carries the standard K', by which the horn K, which carries thework,is raised and lowered. (See Fig. 1.) It is therefore obvious thatthrough the connections described the amount of depression of the horn Kfrom' its highest position to correspond to the thickness'of the workproduces a corresponding amount of elevation of the guides C", andtherefore a corresponding regulation of the height at which t-he feedingof the peg-wire begins, and consequently the length or extent of suchfeed.

From the above it may be seen that the length of the wire fed .down ateach motion is governed b v the distance of the guides C G9 above thestuds Gm C1", since the grasping action takes place when the toggles arereleased from the guides U C, and the cuttingotf action takes place whenthe upper ends of the jaws G C have passed below the studs C10 Cl". Thisfeeding and cutting-off mechanism slides in agroove made in the pieceA5, Figs. 16 and 17, which is secured to the main frame of the machineby screws AT AT A7, Fig. 16. This fixed piece serves also to hold thestud Ain a This stud A", in combination with the spring S, holds thefriction-block A8 against the sliding plate A and presses it (thesliding plate Al) against the fixed way A, so that the whole wirefeeding and cutting mechanism is held in place, unless forcibly actedupon by the positive motion of the machine.

The same downward movement of the lever C3 which feeds and cuts a pegdrives the awl through the stock to form a hole. This is accomplished bythe following mechanism: The outer end of the lever C" carries a pin,d?, and when by the movement of the plate A4, as above described, theawl-bar D has been brought in position to drive the awl through the workto punch the hole, this pin d'2 lies within a slot, d, in the awl-bar,which is arranged to slide vertically up and down through the plate A,which carries it. The machine being so timed that the awl-bar is up whenthe feeding of the wire begins, the same down ward motion of the leverC3 which causes the feeding and cutting off drives the awt-bar downthrough the work, and the upward motion of the lever C withdraws it fromthe work. The hole now having been punched and peg cut off, the nextoperation is to convey the latter, and also the driver E, to a positionwhere they shall be in aline over the punched hole, so that the descentof the driving-bar shall drive the peg. The peg, when cut, enters a slotor hole, IP, in the slide H2 I CU ITO

The same motion which carries the awl out of place and the driver intoplace over the punched hole .in the stock also (by reason ot' the actionabove mentioned, through the lever H, attached to the plate A4) carriesthe slide H" over and upon a xed base-piece or guide, H, until the holeH5 stands over a similar hole, H1 in the piece H, (see Fig. 17,) throughwhich the awl has descended to punch the hole in the work. Then thedescent of the driverbar E drives the eut peg into the work, and thesimultaneous ascent of the clinchingblock N clinches or heads the peg onthe inside.

I will now describe the mechanism by which this motion of the driver-barand clincherblock is obtained. The driver-bar E, like the awl-bar D', isarranged to slide vertically in the plate A.v The drivel-bar is providedwith a slot matching the slot d3 in the awl-bar, before described. Thelateral motion of the plate A* which brings the driver-bar in positionover the hole in the work also brings the slot in the bar intoengagement with the pin d2 on the lever C. Consequently the secondstroke of this lever C depresses and raises the driver-bar in the sameway that the tirst operated the awl. During the operation of thedriver-bar, however, the wirefeeding mechanism is at rest, beingdisconnected from the lever C3.

Simultaneous` action of the clincherN is accomplished in the followingmanner: In operation the boot or shoe is placed upon the upper end ofthe horn K, with the edge under the feed-wheel I and against the gage G,and there held by the pressure of the spring Kl, acting through the rodK, foot-lever K, and links Ki' K3, attached to the collar k, Figs. l, 2,and 3, and standard K. The upper end of this horn K adjusts itself tothe thickness ofthe sole, but is not held rigidly in itsvertiealposition, except when the. shoe is being acted upon by the awl,peg inserting or heading operation. When these are all accomplished,then the horn is freed, so that the shoe-feeding motion may take place.The mechanism for thus fastening' and freeing the horn consists in adevice which locks and unlocks the rod K, this rod K" con trolling thehorn through the foot-lever K. This mechanism consists of a collar, L,Fig. 12, which surrounds the rod K, and is held with a slight elasticityby means of springs L2 and L", so that its motion is very limited. Theobject of allowing this limited motion of the collar L is to prevent auabsolutely abrupt check ofthe motion of the horn. Vhen the grip-lever L"is raised up, the rod K can move freely up and down, subject only to theaction of the spring K1", Figs. l and l0; but when the grip-lever LVl isthrown down it causes the collar L to seize upon the rod K", and thushold it, and through it the horn K. Motion is given to the grip-lever Lby means of the link L", which is pivoted to it by the pin p. The upperend of the link L"h is attached to a lever, L, by a pin, Z, Figs. ll and12, which in turn is operated by the cam LS,

which acts through the pin L7 and gives the desired movement to thelever L6. 1

I will now describe the heading device. This consists of aquadrant-shaped block of metal, N, which swings on trunnions n2 n2,Figs. 4. and 6, and is provided with a projection, N', the upper end ofwhich projects through the opening N2, Fig. 4, so that it may come flushor slightly above the uppersurface of the horn. n is a ridge formed onthe piece N, and is intended to tit in the groove n', Fig. 4:, so as toform a steady-piece. N3, Figs. et and 5, is a lever, the upper end ofwhich rests against the back or underside of the hammerpiece N, and isso proportioned that when the small part N4 otl the hammer-rod N5 is inthe position shown in Fig. 4 it will allow the hammer-piece N to fallback, as shown in Fig. 4;

` but when the hammerrod N5 moves upward it will throw the lower end ofthe lever N backward and the upper end forward, so astto throw thehammerpiece N nearly into the position shown in Fig. -that is, into sucha position that the ha mmcrrod N5 N4 can come immediately under it andgive it a sutiieient blow to head thepeg. Mot-ion is communicated to thehammerrod NA1 N5 by the lever' N, which swings on the pin Nl. The end N8ot"Y the lever N is connected to the rod N" by nuts, which allow thehorn to swing without turning the rod N This rod N9 is attached to alever, Nm, swinging upon the pivot P in the foot-lever K (See Figs. 1and 9;) The lower end ot' the bell'crank lever N1 is connected by alink, P2, and a pivot, P3, to the lever I, which swings upon a pivot,K8, which serves for both the foot-lever I i and the bellcrank lever P".To the end of the lever P, I attach, by means of the pin P", a vert-icalrod, P, which passes up through the center of the main standard A ofthemachine. The mechanism for operating this rod Pi is shown in Fig. 1l^.The upper end of the rod PG is attached by a forked piece, P7, and thepin PS to the lever Pi. This lever P has attached to its lower part aprojection, Pl, which works in a cam-groove, P".

Instead of permitting the ham mer or clincher N to swing so far back asto require a special part-such as N'l-to bring it into place, I torm it,as shown in Fig. S, with ashoulder to arrest its motion when it is swungsu'liticiently ihr back to be out of the way ofthe awl, and yet while itis still within the line of motion of the hain1nerrod. This is one ofseveral modifications that may be made in the mechanical embodiment ofthis part of my invention, which I believe to consist., broadly, incombining with the hollow horn swinging in a circle around its standardan interiorly-located hammer or clincher, which is so constructed thatit may be brought up every time squarely upon the end ofthe peg and indirect opposition to the downward blow of the peg` driver. In allprevious devices ofthis charac ter the construction has been such thatat cer-A tain portions of the work, owing to the angle at IOO IIO

IIS

which the hammer or clincher was presented to the head of the nail, ithas been impossible to give any other than a glancing blow, and inconsequence the work has been very imperfectly performed. By my presentinvention I entirely obviate this difficulty, and thereby furnish animportant improvement in machines of this class.

The final operation is to feed the work along into place for the nexthole to be punched, and I will now describe the mechanism for doingthis: I represents the feed-wheel, which is op erated by a ratchet, l',and pawl I2, Figs. 16 and 17, the pawl I'l being attached to the slideH4 by a pivot, I3, and operated by a spring, I5, Figs. 14 and 17, andlimited in its motion bya check-block, I4, Fig. 17. G, Fig. 14, isaguide and an auxiliary feeding device, it being attached to the slidingplate A4, so as to slide forward at the Sametime, although not in accordwith the feed-wheel I-that is, the friction on the guide G will not beso much as though it were a stationary guide, the slip being reducedabout one-half.

To retain the awl-bar D and driver-bar E in their highest position whennot in engagement with the pin cl2 on the lever-C3, a pair of ribs orprojections, E2 D3, are provided, one of which, D3, enters the slot inthe awl-bar Df, and holds it up when the driver-bar E is engaged by thepin d2, and the other of which, E2, enters the slotin the driver-bar E,and holds it up while the awl-bar is being held up by the same pin. llhelocation and arrangement of this detail are best shown at Fig. 17.

I claim- 1. The combination,with the revoluble horn K, having its upperor working face perforated, of an interiorly located hammer or clineherpivoted thereto,and arranged to swing into and away from the perforationin the horn, as set forth.

2. The combination of the horn K, having a perforated workingface, aswinging hammer a simultaneous to^and-fro movement of the awl, driver,and peg-carrier is obtained, substantially as set forth.

6. The combination,with the horn K and its support or standard K, of thelever K6, carrying the standard and connecting rod K9, rockshaft M',vertically movable guides C, and

rockerarms connecting the rockshaft with the connecting-rod K9, and alsowith the vertically-movable guides G9, whereby motion of the horn up ordown will produce similar motion of the guides C9, all substantially asset forth.

7. The combination of a toggle-bar, C, the toggle C5, the pivotedgrippers and cutters C, and the stud A6,whereby the continued motion ofthe toggle-bar operates to press the grippers against the peg-wire tofeed and cut the peg.
